You CAN'T prove a negative to people like that. And they don't change. They just get worse. OP's life will keep getting worse for the next 80 years. She can get out now or live in hell for the next 70 years. Seems mean of you to wish suffering on her.

Divorce should be the last resort. However, there are some things that make that decision easier (e.g., inability to communicate, lingering trust issues, abuse, etc.). Once you've exhausted your other options, then pressing the "big red button" on the relationship is a viable option.

Not everything is meant to be, despite our insistence to the contrary.

89- There are three very important pieces needed for a successful relationship. You got the first one, communication. The other two are trust and respect. Without mutual trust and respect, no amount of communication will save that train. Eventually it will jump the rails and take multiple innocent people with it.

^ you're absolutely right.
And for the people who didn't get my comment, 'cause obviously some people didn't, OP is in an abusive relationship, and it has gotten so bad that he is able to manipulate and hurt her without actually being there. Trust issues are one thing, making her punch herself out to "prove" that she's faithful is another.

Well, he does care. Not for her, but for himself. He wants to see the footage to quell his own suspicions. This has nothing to do with OP's security/safety while staying late. If he cared about that he would call/have her call just before leaving to make sure she was alright.

Some people are just paranoid. It's not necessarily ops fault. People who have cheated are often paranoid about their partner doing the same. Or maybe his previous partner cheated on him, you never know.

True. I did not think of it like that. But also, if you're going to be so worried about particular things like this, why even have a partner? You would think that since OP said "Husband" they would have trust in each other in the first place.
